b0cc7491c9 crypto: drivers - Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

1c27c0ca22 crypto: jh7110 - Include crypto/hash.h in header file
The header file jh7110-cryp uses ahash_request without including
crypto/hash.h.  Fix that by adding the inclusion.

50c546d70a crypto: jh1100 - Remove prepare/unprepare request
The callbacks for prepare and unprepare request in crypto_engine
is superfluous.  They can be done directly from do_one_request.

Move the code into do_one_request and remove the unused callbacks.

33b53749aa crypto: starfive - fix return value check in starfive_aes_prepare_req()
kzalloc() returns NULL pointer not PTR_ERR() when it fails,
so replace the IS_ERR() check with NULL pointer check.

b3882fa2a1 crypto: starfive - Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

445a4aaf58 crypto: starfive - Add RSA algo support
Adding RSA enc/dec and sign/verify feature for StarFive cryptographic
module. The module only supports mod sizes up to 2048, therefore
calculations more than that will use fallback algo.

48e7fbf662 crypto: starfive - Depend on AMBA_PL08X instead of selecting it
A platform option like AMBA should never be selected by a driver.
Use a dependency instead.

Also remove the depenency on DMADEVICES because the driver builds
just fine without it.  Instead add a dependency on HAS_DMA for dma
mapping support.
